Senior Software Engineer

Senior Software Engineer

As a Senior Software Engineer at Obsidian, you’ll:

Own meaningful product and platform work across Obsidian’s engineering stack. This is a generalist role for someone who can move between backend services, data flows, APIs, product features, integrations, and production systems without getting stuck at the boundaries between them.

You’ll work on systems that help customers understand activity, risk, and threats across their SaaS environments. Some problems will be well-defined. Others will start as a customer need, a security signal, or a vague product idea that needs technical shape. You should be comfortable turning that ambiguity into a design, a plan, and working software.

What you’ll do

• Own features and system improvements from problem definition through production
• Design and build backend services, APIs, data processing workflows, integrations, and product-facing capabilities
• Work with product managers, designers, security researchers, and engineers to turn customer needs into shipped software
• Improve the performance, reliability, scalability, and observability of existing systems
• Make practical technical decisions and explain the tradeoffs clearly
• Help raise engineering standards through code reviews, design discussions, mentoring, and documentation
• Debug production issues and help teams get to durable fixes, not just short-term patches
• Use AI-powered tools effectively while maintaining high standards for correctness, security, and maintainability

What’s in It for You

• Direct impact on a core security product used by enterprises worldwide
• Variety across backend engineering, data pipelines, SaaS integrations, detection systems, cloud infrastructure, and customer-facing workflows
• A chance to work on current security problems around SaaS, identity, data movement, and AI usage
• Strong peers across product, engineering, security research, and go-to-market teams
• A fast-moving environment where senior engineers are expected to own problems, influence direction, and ship

Required Skills & Experience

• 5+ years of experience in a software engineering role
• Strong proficiency in one or more modern programming languages such as Python, Go, TypeScript, or SQL
• Experience designing and building backend services, APIs, distributed systems, data processing workflows, or production product features
• Strong understanding of relational databases such as Postgres
